|“Heh. Sounds pretty tough. But trust me, Nya is worse. Like, so much worse. Let me tell you. I was test driving my newly-built ultimate noodle truck of crime. When for no reason at all, that nosey do-gooder judgey Nya comes out of nowhere and starts messing with me.”|
|— The Mechanic|
The Mechanic is a former employee of Master Chen who was at one point imprisoned in Kryptarium Prison. Prior to the Second Serpentine War, the Mechanic was affiliated with the Anacondrai Cultists, repairing noodle trucks for the underground crime organization. After Chen and his army were banished, the Mechanic went out of business with his employer having been cursed. Due to his involvement with Chen, he was locked up in Kryptarium Prison, where he earned the name "The Mechanic."
After the Battle of Stiix, the Ninja were imprisoned in Kryptarium after being framed for several crimes. Upon entering the prison, they were confronted by the inmates, including the Mechanic, who was vengeful after the Ninja defeated Chen and put him out of work. When the inmates started fighting the Ninja, the Mechanic went after Zane to steal some of his robotic parts, but thanks to P.I.X.A.L. he was stopped from doing so. Following Jay's final wish, the Ninja were never sent to Kryptarium and the Mechanic didn't confront them.
At some point, the Mechanic escaped Kryptarium Prison, but was defeated by Kai and Zane and was subsequently placed back in prison.
Prior to Master Chen's banishment to the Cursed Realm, the Mechanic made money repairing the vehicles of the Anacondrai Cultists. After their defeat at the Corridor of Elders, he was arrested and sent to Kryptarium Prison where he swore revenge on the Ninja with the intent of tearing Zane apart for parts.
When the Ninja arrived at Kryptarium for being framed for a crime spree, the Mechanic opened his and several other inmates’ cell doors, leading them to confront the Ninja. Explaining his situation to Lloyd, he demanded they hand over Zane to use as spare parts in exchange for the grievances he believed the Ninja had caused. However, before he could take any action, Warden Noble arrived, ordering him and Lloyd to shake hands.
During the following meal in the cafeteria, the Mechanic confronted the Ninja again, but was dismissed by them as at most a fourth-tier bad guy. Infuriated, he started a fight during which the Mechanic dragged Zane away, determined to take him apart. However, an electric shock orchestrated by P.I.X.A.L. sent the Mechanic flying back and he was returned to his cell by the guards before he was able to inflict any further damage to the Nindroid.
Due to Jay's final wish, the Mechanic never confronted the Ninja in Kryptarium, due to them never being sent there.
The Mechanic manages to somehow break out of Kryptarium Prison and fights Kai and Zane with a new arm that is similar to a flamethrower. However, Zane manages to freeze the villain in place, and then send him back to the Kryptarium.
The Mechanic was seen in the Kryptarium Prison several times, sharing one cell with a Sons of Garmadon member, watching the fight between Cole and Giant Stone Warrior, and later throwing random objects at Cole, for defeating and placing Giant Stone Warrior and Killow back into their cells.
While in the exercise yard, a newspaper comes at the Mechanic, who reads it, and discovers that the Ninja are gone before relaying the news to Ultra Violet, who tells him they breakout after lights out. Later that night after the guards turned off the lights, the Mechanic used his cybernetic arm to get the keys to his and Ultra Violet's cells before they escape through a tunnel she had dug. Once they reached the sewers, the Mechanic and Ultra Violet argue about who they thought was the worst (Zane or Nya) before Fugi-Dove shows up, telling them it is Jay. Once they heard Ultra Violet's story about her capture, the Mechanic tells her and Fugi-Dove about the time Nya stopped him and later stole his truck before eventually listening to Fugi-Dove's story about his hatred for Jay, only to easily find it false, until they reach a grate, and start to make plans for crime breaking, only to end up captured by Samurai X when they had inadvertently triggered her hidden sensors, resulting in the three recaptured prisoners to proclaim her as the worst.
It is shown that he has managed to escape prison once again.
